What is an example of system software?
Windows is your operating system as in "System Software". Some systems have Bluetooth enabled in them. Here Bluetooth is a system software of the computer. If you want to be clever, you could say your BIOS, or DOS or Linux.
The largest chuck of available memory that is not fragmented.
Why operating system needed in a computer?
An operating system is always needed in a computer. It is like a surface where you can install your softwares. Without it, computer hardwares like the hard disk or Random access memory etc can not load the softwares itself.
All the operating systems work like each others. There are no major differences in these.
What is the next upgrade after Mac OS X 10.3.9?
The next version of Mac OS X after 10.3.9 is Mac OS X 10.4 "Tiger." The latest updated version of Tiger is 10.4.11.
Apple supports Mac OS X 10.4 on Macs running PowerPC G3 or higher processors with a speed of 400MHz or faster and a built-in DVD-ROM drive.
Difference between realtime and multiprocessor scheduling?
uniprocessor :
- A type of architecture that is based on a single computing unit. All operations ( additions, multiplications, etc ) are done sequentally on the unit.
. multiprocessor :
- A type of architecture that is based on multiple computing units. Some of the operations ( not all, mind you ) are done in parallel and the results are joined afterwards.
What is it called when two operating systems are installed on the same computer?
There are three main terms when referring to a computing machine without multiple operating systems (OSs). "Dual boot" OSs offer the operator a choice between them at start-up. There are also "virtual machines" in which the primary OS is running while the second is open in a separate window simultaneously. The third is a machine with a "hard partition" with both OSs installed in two separate parts of the disk.
What is cascading process termination?
Some systems, including VMS, do not allow a child to exist if its parent
has terminated. In such systems, if a process terminates (either normally or
abnormally), then all its children must also be terminated. This phenomenon,
referred to as cascading termination.
EMP: when you use embedded systems, it would be better to better off since it's focus on a particular task than multiple tasks.
How do you rename files in QNX?
QNX's shell is POSIX compliant, so you can use Unix commands on the system. To "rename" a file, you move it. mv oldfilename newfilename is equivalent to renaming the file.
Remote Installation Services (RIS)
How can you start any of the accessories in windows operating system?
you can start any of the accessories from the start menu then go to all programs and then you will find accessories.
Hope i helped
Example of network operating system?
A network operating system, NOS helps computers act as servers while giving them network operation capabilities user administration, print and file sharing and client server features. Examples of network operating systems are Microsoft Windows Server, Linux, Sun Solaris and Novell Netware.
What are the four characteristics of an operating system that falls under a commercial license?
The four characteristics of an operating system that falls under a commercial license are: the software does not have a warranty, it is free to distribute to users. Meaning it can be used for an organization, or school without having to buy the software multiple times. It is free to modify as the user permits, and distribute.

int x, y;

Is operating system a machine dependent or independent?
An OS is never machine dependent, meaning that is can run on multiple machines. It can be however architecture or platform dependent, meaning that it runs on specific types of machines only (e.g.: Intel, AMD64, PPC etc.)
There are few OS's who can claim to be platform independent in that they can run (perhaps with some minor adaptations) on any platform that satisfies some rather general criteria (related to computing power, availability of a compiler etc.).
GNU is a Unix-like operating system created and funded by the Free Software Foundation. One of the goals of the Free Software Foundation was an operating system composed entirely of free software. Many pieces, such as shells, utilities, and compilers were created for this purpose. The GNU operating system has yet to be fully completed, due to slow development and debates about design goals. Most of the programs created for GNU have been ported to other kernels and operating systems, most notably Linux.
Note: This question refers to an operating system. For the animal, see 'What is a gnu?' in the Related questions section below.
Well, there are several reasons why it wouldn't boot to the OS. You could not have enough RAM to support the OS. If the CPU is overclocked too far it will not boot to the OS (heat or bus compatability issues) If the OS is unstable, or somehow the Kernel got altered (A Reformat would fix this) If you havn't reformatted since you installed the new MOBO, alot of times the OS will not boot There are a few others which i doubt apply to you, but I would try reformatting as this will most likely fix the problem. (Go into the BIOS and check your CPU temp, it should be running around 30, or 40 degrees Celcius) The operating system, which thought it was running on one lot of hardware, suddenly finds itself running on completely different hardware. It needs to be reinstalled so that it can configure itself for the new hardware. You can replace something like the hard drive or memory chips without that being necessary, but certainly not the motherboard.
Explain the function of each of the four system resources that software uses to manage hardware?
